Control and monitor GPIO on remote device (32u4) with local console (M5Stack ESP32) over LoRa

LoRa-GPIO

This is a main container solution of several other projects for remote control and monitoring of GPIO pins on a demote device from a local console using LoRa.

Normally, one might code in only this main solution, however unresolved conflicts arose when uploading binary to different COM ports in different projects. So for now, the projects contained in this solutions are opened in different instances of Visual Studio 2017 with the VisualMicro add-in installed.

and: https://gojimmypi.blogspot.com/2018/02/m5stack-lora-range-issues.html

The 4 main projects of interest:

Console

32u4 based DIYMALL LoRa32u4 using RadioHead library with good range as local control console. There's currently no display implemented on this Console

Device

32u4 based DIYMALL LoRa32u4 using RadioHead library with good range as remote GPIO device.

M5StackConsole

ESP32 based M5Stack LoRa that initially was working with Sandeep Mistry's LoRa library, but had rather poor range. The M5Stack has a nice enclosure and built-in display.

The working, but poor range code can be found here (NOTE it was saved with frequency=433.375E6): https://github.com/gojimmypi/LoRa-GPIO/blob/8e96d83eca89cd9ac19fb5eeca8fb276b7a5dddf/M5StackConsole/M5StackConsole.ino

The current objective is to get the RadioHead library working with this project.

See the M5-RadioHead branch for this project: https://github.com/gojimmypi/LoRa-GPIO/tree/M5-RadioHead

The 11-month old Adafruit fork of RadioHead: https://github.com/gojimmypi/RadioHead/tree/development

The Master RadioHead overwritten with working download from Adafruit tutorial (missing ESP32 support) https://learn.adafruit.com/adafruit-feather-32u4-radio-with-lora-radio-module/using-the-rfm-9x-radio which can be found on this local fork branch: https://github.com/gojimmypi/RadioHead/tree/master

Then new changes to most recent code will be applied to the M5Stack local branch: https://github.com/gojimmypi/RadioHead/tree/M5Stack (not yet updated with most recent, 11-month old code)

See source "A github'ified version of http://www.airspayce.com/mikem/arduino/RadioHead/": https://github.com/adafruit/RadioHead

RogueDeviceTest

We'll want to ignore transmissions from 3rd party devices. This is an example 3rd party.

M5StackConsole-bad

something went amuck here and could not be resolved. Code moved to new project. Error: VM_Boards.h: 653:2: error: #error "Please edit Boards.h with a hardware abstraction for this board" error "Please edit Boards.h with a hardware abstraction for this board" for (analogPin = 0; analogPin < TOTAL_ANALOG_PINS; analogPin++) ... Error compiling libraries Debug Build Error: This hardware might not support the default Visual Micro Debugger. If this project is using OTA/WiFi upload then please use the vMicro>Debugger menu to set the Serial COM and Remote port for the debugger. Otherwise switch the toolbar from 'Debug' to 'Release' and build again. or switch off Automatic Debugging or configure the SoftwareSerial debugger option. Debug build failed for project 'M5StackConsole'

Answer: "The debug issue was that you had enabled automatic analog, digital or other graphical views in the debug options for the project. These views require information about the board such as number of digital pins. Your hardware is unknown hence the "error" telling you the hardware is unknown."

See http://www.visualmicro.com/forums/YaBB.pl?num=1518378800/0#3

(but I don't actually know how to fix this in the IDE; this -bad project saved for that)

Also note: "Yes v10 of the USB driver is not for your op sys it is for windows universal" http://www.visualmicro.com/forums/YaBB.pl?num=1518378800/2#2

Apparently I had not read the full description properly and inadvertantly installed the most recent "Universal" drivers that don't work well with Windows 10. :|

Installation

Download Library

Using the Arduino IDE Library Manager

1. Choose Sketch -> Include Library -> Manage Libraries...
2. Type m5stack into the search box.
3. Click the row to select the library.
4. Click the Install button to install the library.
5. Click "File-> Examples". Here are some test programs in "M5Stack->"

Using Git (most environments)

cd ~/Documents/Arduino/libraries/
git clone https://github.com/gojimmypi/RadioHead.git
git clone https://github.com/gojimmypi/M5Stack

Using Git (Windows)

c:
cd %USERPROFILE%\documents\libraries
git clone https://github.com/gojimmypi/RadioHead.git
git clone https://github.com/gojimmypi/M5Stack
